Retraction: Yang, C., et al. miR-126 Functions as a Tumor Suppressor in Osteosarcoma by Targeting Sox2. Int. J. Mol. Sci. 2014, 15, 423–437, doi:10.3390/ijms15010423

Experimental results from [1] were found to be unreliable. In particular, the authors have attempted to replicate the real-time PCR and Western blot experiments but were not able to obtain the same results. All of the authors have agreed to the retraction of the paper [1], which will thus be marked online as retracted. The International Journal of Molecular Sciences is a member of the Committee on Publication Ethics (COPE) and takes very seriously the responsibility to enforce strict ethical policies and standards.
